Table 1. Parameter values used in the simulation experiment. Move length values (Mstm, Mfor, Mpas) are mean distances (in meters) from exponential distributions. Turn-angle values are concentration parameters (Tstm, Tfor, Tpas) from circular-normal distributions with means = 0. Pmv values are probabilities of individual damselflies moving away from streams in a single time step. Simulations were run with each combination of M, T, and Pmv. To reduce complexity, the M and T parameters were not varied independently. Level refers to the different parameter values used in the experiments (three for M and T and four for Pmv). Level-2 M and T parameters approximate observed values for each habitat type. Level-1 Pmv parameters are the observed values for each landscape type: forested (FO), partially forested (PF), and nonforested (NF).
